To @ZZ whom it may concern:

ne itknown that l', (E1-metes L. Porn, of the city ofBnffalo, in the county of Erie and State of New-York, have invented a new and useful Improvement in Metallic Seals, of which the following is a specification.

IThis invention relates to an improvement in that class of seals which are employed for securing the doors of frei glitears, and for sealing packages, Src., and which consist ci' a narrow strip of tin or other suitable metal having its ends provided with means whereby they can be interlocked.

The object of my invention is to construct a seal of lthis character which can be easily and quickly applied, and the ends of which, when locked together, cannot be stripped or separated 'and again replaced without being detected. n f

My invention consists, to these ends, of the improvements in the construction of the seal which will be hereinafter fully described,and pointed out in the claims.

In the aocoinpnnying drawings, Figure l represents a perspective viewol" my improved seal with the ends separated. Fig. 2 is a similar view with the threading end inserted through the slot in the opposite end of the strip, preparatory to pressing thesanie. Fig. 3 is a longitudinal section of the seal with the ends interloeked, but not pressed down. Fig'.

' 4 is a siinilarview,on an enlarged seule, showing the ends pressed down. Fig. 5 is a face view oi' the seal after being pressed. Fig. G is a perspective View of a inediiied construetion of the seal. Fig. 7 is a similar View of the suine seal, showing the ends interlocked end in position to be pressed. Fig. 8 is a longitudinal section of the seal illustrated in Figs. (i and 7, with the ends pressed down. Figs. 9 and l0 are kperspective views oi another modified construction of the seal.

Like letters of reference refer to like parts in the several figures. f-

A represents the body of the seal, which is composed of a narrow strip ol" tin or similar niet-al. The strip A is provided near one end with a U-shaped slot, u, which is adapted to receive the opposite end,b,ot` the strip, which is made correspondingly Us! apcd in crossseetion. The threading ond l) is formed by cutting transverse slits into opposite sides of the strip .-IL, and then bending up the sides bi' ofthe strip between the cuts b and the end oi' the strip, so that the sidcsl will be ut right angles, ortl1ereabout,with the center portion, b, 0i' the strip, thus forming a trough-shaped or channeled threading end. This threading end o is providedou its center portion,b,with a tongue or lip, c, which is formed by cutting a U-shaped slot, c", into the center portion, o, and raising the lip so formed on the lint heck oi" the trough -shnpcd threading end. rlhe tongue e is adapted to enter an opening or slot,d, formed in the opposite end of the strip A, above the Ushapod slot u. The sides of the slot c whereby the tongue c is formed are preferably recessed or out into the sides If, sov

that when the seal is pressed the portion o Hof thestrip etween die slotsn'nnd `@will rest in the recesses of thc slot 1^ und permit the tongue c to be pressed llush with the strip. The threading end b is inscrled in the U -shaped slot u. until the shoulders c ol' the threading end tre brought in line with the neuter or transverse portion of the sloi u, und the free end of the tongue c hus passed by thetransverse slot d. of the threading endl; in the slot u the tongue c is caused to engage in the slot d, :is repre sented in Figs. L und JS. "lhe sides Ir' ol' the threading end b are nou' bent outwardly and pressed against the outer side of the strip A, and the tongue or lip e uga-inst the opposite side ol' the strip, represented in Figs. 4

By '.1 short backward movementv and '5. The pressing ol' thc seul is aoeo1ny plished by a suitable press. 1u this manner the ends ofthe strip uro securely inici-locked, and cannot be separated or stripped without being detected.

'if preferred, the longue or lip c muy be formed at the upper endet' the trmlglrshnpcd threading end Za, and passed through tho opening (land bent inwardly against the strip A, as shown in Figs. 6, Y, und S.

The tongue or lip u may be onnited, if preferred, ns shown iu Figs. il und l0, and in this case the slotted end ol' the strip is formed with an cxtension,f, which is lapped over the sides b of the trough-shapei'l thrafnding ond nl'tcr the sides be have been p: "sul agniust the strip.

The strip i\,wirh its slots :unl l hreodiug end,

is formed at one operation by suitable etrmp irre-dies. f

My impreved Seel is very simple in con! struetion, und can be eaeily threaded in the dark. I claim 21e my invention@ 1. A metellie seal composed of ai strip of tin or other euitebe metzih provided abone euri with :L troughsimped threading emi having; eides, and :iii ite opposite end with :i U- shfrped elotedopted ro receive the trough shaped threading eed, substantially as eet forbh.-
